        5.1 RESTRICTION ON INTERESTS. During the period commencing at the
        Distribution and continuing until January 1, 2004, subject to the
        express terms of written agreements to which Leap is a party in
        existence at the time of the Distribution:

                      (a) Leap and its Affiliates shall not acquire Interests,
        directly or indirectly, in Persons that deploy (or intend to deploy) a
        Wireless System outside the United States unless (i) with respect to
        Persons that do not have a pre-existing Wireless System that utilizes a
        technology other than cdmaOne, such Person only utilizes or intends to
        only utilize cdmaOne for such Wireless System and such Person agrees to
        procure infrastructure and subscriber equipment from QUALCOMM in
        accordance with the provisions of the Equipment Agreement, or (ii) with
        respect to Persons that do have a pre-existing Wireless System that
        utilizes a technology other than cdmaOne, the provisions of the last
        sentence in this Section 5.1 are complied with as to such Person and
        such Person agrees to procure infrastructure and subscriber equipment
        from QUALCOMM for such Person's cdmaOne Wireless System in accordance
        with the provisions of the Equipment Agreement; and

                      (b) Leap shall use commercially reasonable efforts to
        cause each Related Entity that is not a Leap Affiliate to not acquire
        Interests in other Persons that deploy (or intend to deploy) a Wireless
        System outside the United States unless such Person only utilizes or
        intends to only utilize cdmaOne for such Wireless System and such Person
        agrees to procure infrastructure and subscriber equipment from QUALCOMM
        in accordance with the provisions of the Equipment Agreement.

        Notwithstanding the provisions of this Section 5.1, an Interest may be
        acquired in a Person that has a pre-existing Wireless System that

        are to be used by such Person solely to support and in connection with
        the deployment of a cdmaOne Wireless System, (ii) reasonable efforts are
        made to ensure that such proceeds are so utilized, and (iii) unless such
        Person is already a party to an equipment requirements agreement with
        QUALCOMM (in accordance with the provisions of the Equipment Agreement),
        the efforts described above are undertaken to have such Person agree to
        procure infrastructure and subscriber equipment in accordance with the
        provisions of the Equipment Agreement. The parties agree that this
        Section 5.1 shall not restrict Leap's investments in operating companies
        in the United States.

        5.2 RESTRICTION ON USE OF OTHER TECHNOLOGY Leap agrees that during the
        period commencing at the Distribution and continuing until January 1,
        2004, subject to the express terms of written agreements to which Leap
        is a party in existence at the time of the Distribution:

                      (c) Leap will solely implement and utilize cdmaOne in

                      (d) Leap will cause its Affiliates that do not have a
        pre-existing Wireless System that utilizes a technology other than
        cdmaOne to solely implement and utilize, cdmaOne in connection with each
        such Affiliate's Wireless Activities;

                      (e) Leap will cause its Affiliates that do have a
        pre-existing Wireless System that utilizes a technology other than
        cdmaOne to solely implement and utilize cdmaOne in connection with each
        such Affiliate's Wireless Activities to the extent those Wireless
        Activities are funded, directly or indirectly, by Leap, and furthermore
        Leap shall exercise commercially reasonable efforts to cause such
        Affiliates to use cdmaOne or a cdmaOne overlay with respect to any
        expansions of each such pre-existing non-cdmaOne Wireless System; and

                      (f) Leap will use its commercially reasonable efforts to
        cause each Related Entity (that is not a Leap Affiliate) to solely
        implement and utilize cdmaOne in connection with each such Related
        Entity's Wireless Activities.

        Except to the extent set forth in clause "(c)" of the immediately
        preceding sentence with respect to Affiliates having pre-existing
        non-cdmaOne Wireless Systems, (i) in no event will Leap or its
        Affiliates implement, utilize or support in any respect global system
        for mobile communications ("GSM"), time division multiple access
        ("TDMA") or any other digital technologies (or variants thereof) in
        competition with cdmaOne in connection with the provision of wireless
        communication services outside the United States, and (ii) Leap agrees
        to exercise its commercially reasonable efforts to cause any Related
        Entity not to implement, utilize or support in any respect GSM, TDMA or
        any other competing digital technologies (or variants thereof) in
        competition with cdmaOne in connection with the provision of wireless
        communication services outside the United States. Leap further



                                       2

        agrees to, and agrees to cause its Affiliates to, support and promote
        cdmaOne based technology for commercial implementation by its corporate
        partners and any consortium of which it is a member in connection with
        any Wireless Activities engaged in by any such partners and/or consortia
        in all parts of the world other than the United States. The parties
        agree that this Section 5.2 shall not restrict Leap's investments in
        operating companies in the United States or the technology choices of or
        equipment deployment by Leap or operating companies in the United
        States.

        2. EFFECT ON CREDIT AGREEMENT. The Parties agree that there are no
provisions in the Credit Agreement dated as of September 23, 1998 (the "Credit
Agreement"), by and between QUALCOMM, Leap and ABN AMRO BANK N.V., as
Administrative Agent which would have the effect of continuing the obligations
of Leap removed as a result of the amendment set forth in Section 1 above. If
and to the extent that such restrictions do exist in the Credit Agreement, the
Parties terminate and permanently waive such restrictions.

        3. FULL FORCE AND EFFECT; ENTIRE AGREEMENT. Except to the extent
expressly provided in this Amendment, the terms and conditions of the Separation
